14:32-6
14:32 They came to a place which was named Gethsemane. He said to his disciples, “Sit here, while I pray.” 14:33 He took with him Peter, James, and John, and began to be greatly troubled and distressed. 14:34 He said to them, “My soul is exceedingly sorrowful, even to death. Stay here, and watch.”
14:35 He went forward a little, and fell on the ground, and prayed that, if it were possible, the hour might pass away from him. 14:36 He said, “Abba, Father, all things are possible to you. Please remove this cup from me. However, not what I desire, but what you desire.”
15:33-4
15:33 When the sixth hour had come, there was darkness over the whole land until the ninth hour. 15:34 At the ninth hour Jesus cried with a loud voice, saying, “Eloi, Eloi, lama sabachthani?” which is, being interpreted, “My God, my God, why have you forsaken me?”
n.b.: 15:34 is quoting the opening of Psalm 22.
These two examples of Jesus praying are very different from the textbook example of “how to pray” given in the Lord’s Prayer (Matthew 6:9-13, Luke 11:2-4).
Here Jesus seems to be showing very human feelings of weakness and despair, and opening himself up to God for strength and guidance.
